Which of the following is true regarding transdermal patches?
The patch should always be placed in the same location.
The nurse can discard these medications in the trash can.
These patches can be placed anywhere on the body.
The nurse should always wear gloves when handling these medications.
The Correct Answer is D
Choice A rationale
Placing the patch in the same location repeatedly can lead to skin irritation, reduced absorption due to stratum corneum thickening, and localized adverse reactions. Rotation of application sites allows the skin to recover, maintains optimal drug absorption, and prevents cumulative dermal irritation.
Choice B rationale
Transdermal patches often contain significant amounts of medication, including controlled substances or potent drugs. Discarding them in the trash can poses risks of accidental exposure to others, environmental contamination, and diversion. Proper disposal protocols, such as flushing or returning to pharmacy, are crucial.
Choice C rationale
While transdermal patches are designed for systemic absorption, specific sites are recommended to optimize efficacy and minimize adverse effects. Areas with less hair, intact skin, and good circulation are preferred. Improper placement can lead to erratic absorption or local irritation, reducing therapeutic benefit.
Choice D rationale
The nurse should always wear gloves when handling transdermal patches to prevent direct skin contact with the medication. Many transdermal drugs can be absorbed through the nurse's skin, leading to unintended pharmacological effects or sensitization. Gloves provide a crucial barrier against dermal absorption.

Correct Answer is ["25"]
Explanation
Step 1 is to determine the total infusion time in minutes. 1 L = 1000 mL. 1000 mL ÷ (150 mL/h) = 6.666. hours. 6.666. hours × (60 min/hour) = 400 minutes.
Step 2 is to calculate the flow rate in drops per minute. (1000 mL ÷ 400 min) × (10 gtts/mL) = 25 gtts/min. The flow rate is 25 gtts/min.
Correct Answer is ["A","B","C","D"]
Explanation
The aortic valve is best auscultated at the second intercostal space (ICS) along the right sternal border. This anatomical landmark corresponds to the superficial projection of the aorta and is where the sounds of aortic valve closure and blood flow through the aorta are most clearly transmitted to the chest wall. Optimal sound transmission is achieved by minimizing intervening tissue. Pulmonic rationale:
The pulmonic valve is best auscultated at the third intercostal space (ICS) along the left sternal border, also known as Erb's point. While the pulmonic area is typically at the second ICS left sternal border, Erb's point provides a broader area for detecting murmurs related to both the pulmonic and aortic valves. This location provides good sound transmission for the pulmonary artery. Tricuspid rationale:
The tricuspid valve is best auscultated at the fourth intercostal space (ICS) along the left sternal border. This location overlies the right ventricle and the tricuspid valve, allowing for clear detection of its closure sounds and any associated murmurs. The proximity of the valve to the chest wall at this point facilitates optimal auscultation. Mitral rationale:
The mitral valve is best auscultated at the fifth intercostal space (ICS) at the midclavicular line (MCL). This location is also known as the apex of the heart, where the left ventricle's impulse is strongest. Sounds produced by the mitral valve, particularly during its closure, are best heard here due to the direct anatomical projection and maximal cardiac impulse. .
